w'mnw WASHER This invention relates to a windowwashing machine and it.alms to providea novel construction whereby awmdow while 1n asubstantially"V closed position maybe washed f .5J on the outside by theoperation of mechanism from tlieinside'of la building.

Itis further aimed to provide a novelconstruction attachable to a windowsash and in @3 which the operatingl partsare rotatably and slidablylmounted. e V i Another object is toprvide a novel clon-g struction inwhich the brush or washing ele.-j

ment will be moved over every part of awin-i l Figure 1 is a viewshowing the inventionin-v" side elevation and applied to awindow, the i,
